According to the mv88e6060 datasheet, the first mac byte must be at position 9 instead of 8 since the bit 8 is used to select if the mac address must differ for each port for Pause frames. Use the correct shift and set the same mac address for all port. Signed-off-by: Neil Armstrong <redacted> --- drivers/net/dsa/mv88e6060.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
